Reversible photoresponsive switching in Bi2.5Na0.5Nb2O9-based luminescent ferroelectrics†
Abstract
Reversible luminescence modulation upon photochromic reactions with excellent reproducibility was achieved from Eu3+ doped Bi2.5Na0.5Nb2O9 multifunctional ferroelectrics. The material exhibits strong sensitivity to visible light or sunlight with fast response time without inducing any structural changes.
